Out of the 40 cities where Google offers is currently available, customers in 23 of these now get offers from the company's partners in addition to Google's own offers.

In its announcement, Google explicitly acknowledges that in order to bring its users the best deals, it needs to work with partners. At the same time, though, it's also clear that these smaller niche sites need bigger partners to have any chance in succeeding in a market that is dominated by Groupon and LivingSocial.

Maybe the most interesting of these new partners is Signpost (which, it is worth noting, is partly funded by Google Ventures). The company sets up online stores for small businesses and also works with its customers to set up daily deal campaigns.
